Attachment for tractor wheels



'Jan. 23, 1940. v. M. GILKERSON ATTACHMENT FOR TRACTOR WHEELS Filed Nov.24, 1937 V: M. g z'lfiersan Patenteddan. 23, 1940 UNITED STATES PATENTOFFICE 2 Claims.

This invention relates to an attachment for tractor wheels adapted toprevent the wheels from sliding laterally.

An important object of this invention is to provide an attachmentespecially adapted for the front wheels of tractors, having pneumatictires, to prevent the front wheels from sliding laterally when movingacross an inclined surface.

Another object of the invention is to provide a disk mounted on one sideof the tire, in spaced relationship thereto, to cut into the surfaceover which the wheel is moving to prevent lateral. slippage of thewheel.

A further object of the invention is to provide means whereby theattachment may be readily applied or removed.

Other objects and advantages of the invention. will hereinafter becomemore fully apparent from. the following specification of which thedrawing forms a part, and wherein- Figure l is a side elevational viewof the inside of a tractor wheel showing the attachment applied thereto,

of the attaching member formed of the corresponding sections, and

Figure 5 is a sectional view on the line ,55- of Figure 4.

Referring more particularly to the drawing wherein like referencecharacters designate likeor corresponding parts throughout, I0designates a front wheel of a conventional tractor having a pneumatictire H mounted thereon.

A disk 12 which is of substantially greater circumference than tire H isprovided with an annular flange I3, of substantially the same diameteras wheel Ill, which extends outwardly from. one side of disk l2 andwhich is adapted to engage against the outer side of the wheel 10 tohold disk l2 spaced from tire II as best seen in. Figure 2.

Disk I2 is provided with a central opening l4- having the slots l5extending therefrom. Open-- ing I4 is adapted to receive the hub 16 ofwheel. [0 which encloses the end I! of the axle on which hub I6 ismounted to rotate. Slots l5 are provided to accommodate the ribs whichare formed. on the hubs 16 of some of the conventional tractor wheels. Anut and washer l8 and [9 respectively engage the reduced threaded end 20of axle: 11 to assist in securing disk [2 in position.

A disk 2|, provided with a central opening 22 and comprising thesections 23 and 24 having tongues 25 adapted to overlap and connect thesections 23 and 24, is "mounted on the inside of wheel I0 with theopening 22 adapted to accom- 5 modate the axle ll. Disk 2| is ofsubstantially the same diameter as wheel l0 and is provided with spacedopenings 26 to receive the bolts 21 which extend through wheel l0 andthe spaced openings 28 in disk l2. Nuts 29 are secured to the threadedends of bolts 21 to secure disk l2 to disk 2| and wheel l0.

Section 23 is provided with a slot 30 to aline with an opening in wheell0 through which the tire valve 3| extends. 1

From the foregoing it will be obvious that disk 12 can be removed byremoving nuts and bolts 29 and 21, the sections Hand 24, and the nut andwasher l8 and I9. Disk 2| being formed of two sections permits theattachment to be quickly applied or removed without removing the wheel.With disk 12 in position the tractor may move crosswise of a field whichis slippery without danger of the tires H sliding laterally since diskl2 will cut into the earth to resist any lateral 25 movement. The diskI2 is spaced from tire H to allow it to flex under the tractors weight.In passing over a hard surface the front wheels will ride on the edge ofdisk l2 so that a substantial connection such as described is necessary.

The attachment may be used on other vehicles besides tractors and may beused on rear wheels in some cases. The invention as illustrated isadapted to be attached to one particular com- 35 mercially builttractor. Slight changes and modifications may be required to adapt theinvention to other makes of tractors having differently shaped and sizedwheels.

It is to be understood that various modifications 4 and changes may beresorted to without departing from the spirit and scope of theinvention.

I claim as my invention:

1. In combination with a wheel having a pneumatic tire, a disk providedwith a central opening adapted to engage the hub of the wheel, an annu-'lar flange, formed integral with and projecting outwardly from one sideof the disk, to engage the wheel to hold said disk in spacedrelationship to the tire, a plate formed of corresponding sectionsadapted to be positioned on the opposite side of said wheel, andfastening means removably connecting the disk and plate to retain theparts in position on the wheel, said disk being of greater diameter thanthe tire to engage a supporting 56 surface to prevent sidewise movementof the tire.

2. In combination with a wheel having a pneumatic tire, a disk having aplurality of openings, a flange extending from one side of said diskadapted to engage the wheel to hold the disk in spaced relationship tothe tire, a disk formed of corresponding sections for engaging theopposite side of the wheel and provided with a plurality of openings,and fastenings extending through the openings in said sections and inthe first mentioned disk and through the wheel to secure said firstmentioned disk to the wheel; said first mentioned disk being of agreater diameter than the tire to engage the earth to prevent lateralslippage of the tire.
